[Vajrasky Kok]

Vajrasky Kok added the comment:

Attached the unit test.

Here is the simpler script to product the bug:

------------------------
import argparse
parser = argparse.ArgumentParser(prog='PROG')
parser.add_argument ('--a', metavar='a'*76)
parser.add_argument ('--b', metavar="[innerpart]outerpart")
parser.add_argument ('c', metavar='c'*76)
parser.add_argument ('d', metavar="[innerpart2]outerpart2")
args = parser.parse_args()
------------------------

python thefile.py --help
